And definitely you will possibly get infected by one more runny nose virus, because there are over 300 different runny nose viruses. But you will certainly unlikely get the same runny nose virus that you had in the past because you have created immunity to that virus.Grownups have previously had a lot of the rhinitis viruses. Grownups have established resistance to the ones they have had. So there are not so many runny nose infections remaining for parents to catch. That is why adults only acquire a few colds each year whereas kids get a dozen colds annually.
